About

The Airplane Guy, Hardy Cheung is a corporate trainer who makes things happen for corporations. He experiments with various paper airplanes made by him with deep knowledge and interest for airplanes as a hobby.

With the planes he made, he creates various overwhelming stunts which will fly as far as 30m and helicopter planes that can fly up high and stay up for long.


Leonardo da Vinci



The first form of man-made flying objects were kites. The earliest known record of kite flying is from around 200 B.C. in China, when a General flew a kite over enemy territory to calculate the length of tunnel required to enter the region.Leonardo's (15th century) dream of flight found expression in several designs, but he did not attempt to demonstrate flight by literally constructing them.

 



However, this was only an experimental design and was never put into practical use. Da Vinci was in this instance no more than an experimental engineer, putting onto paper age-old principles. Without adequate technology the ability to create such machines was virtually impossible during this time.



Da Vinci's vaunted spiral design created in 1490, called the Helical Air Screw, has often been cited as the first serious attempt to produce a working helicopter. Da Vinci himself quoted on the device: "...I have discovered that a screw-shaped device such as this, if it is well made from starched linen, will rise in the air if turned quickly...".
Wright Brothers


Experiments with gliders laid a groundwork to build heavier-than-air craft, and by the early 20th century advancements in engine technology and aerodynamics made controlled, powered flight possible for the first time.

Following a step by step method, discovering aerodynamic forces then controlling the flight, the brothers built and tested a series of kite and glider designs from 1900 to 1902 before attempting to build a powered design. The gliders worked, but not as well as the Wrights had expected based on the experiments and writings of their 19th century predecessors. The Wrights constructed their own wind tunnel and created a number of sophisticated devices to measure lift and drag on the 200 wing designs they tested. As a result, the Wrights corrected earlier mistakes in calculations regarding drag and lift. Their testing and calculating produced a third glider with a larger aspect ratio and true three-axis control. They flew it successfully hundreds of times in 1902, and it performed far better than the previous models. In the end, by establishing their rigorous system of designing, wind-tunnel testing of airfoils and flight testing of full-size prototypes, the Wrights not only built a working aircraft but also helped advance the science of aeronautical engineering.





The Wright Flyer: the first sustained flight with a powered, controlled aircraft. The Wrights appear to be the first design team to make serious studied attempts to simultaneously solve the power and control problems. Both problems proved difficult, but they never lost interest. They solved the control problem by inventing wing warping for roll control, combined with simultaneous yaw control with a steerable rear rudder. Almost as an afterthought, they designed and built a low-powered internal combustion engine. Relying on their wind tunnel data, they also designed and carved wooden propellers that were more efficient than any before, enabling them to gain adequate performance from their marginal engine power.

Although wing-warping was used only briefly during the history of aviation, when used with a rudder it proved to be a key advance in order to control an aircraft. While many aviation pioneers appeared to leave safety largely to chance, the Wrights' design was greatly influenced by the need to teach themselves to fly without unreasonable risk to life and limb, by surviving crashes. This emphasis, as well as marginal engine power, was the reason for low flying speed and for taking off in a head wind.

The Wright brothers. The first flight by Orville Wright, of 120 feet (37 m) in 12 seconds, was recorded in a famous photograph. In the fourth flight of the same day, Wilbur Wright flew 852 feet (260 m) in 59 seconds. The flights were witnessed by three coastal lifesaving crewmen, a local businessman, and a boy from the village, making these the first public flights and the first well-documented ones.

Performance (rather than safety) was also the reason for the rear-heavy design, because the canard could not be highly loaded; anhedral wings were less affected by crosswinds and were consistent with the low yaw stability.

Experiments with gliders laid a groundwork to build heavier-than-air craft, and by the early 20th century advancements in engine technology and aerodynamics made controlled, powered flight possible for the first time.

Amelia



Amelia (born July 24, 1897) was a noted American aviation pioneer and author. Earhart was the first woman to receive the Distinguished Flying Cross, awarded for becoming the first aviatrix to fly solo across the Atlantic Ocean. She set many other records, wrote best-selling books about her flying experiences and was instrumental in the formation of The Ninety-Nines, an organization for female pilots.
Balloonist



Aerostation, as ballooning is commonly called, began more than two centuries ago, when the first balloons rose above France near the end of the 18th century. The Montgolfier (hot air) and Rozier (gas) balloons flew within ten days of each other in 1783. Two hundred years later, in 1999, Bertrand Piccard and Brian Jones flew a balloon for the first time around the world.

With the efforts to analyze the atmosphere in the 17th and 18th century, gases such as hydrogen were discovered which in turn led to the invention of hydrogen balloons. Various theories in mechanics by physicists during the same period of time—notably fluid dynamics and Newton's laws of motion—led to the foundation of modern aerodynamics. Tethered balloons filled with hot air were used in the first half of the 19th century and saw considerable action in several mid-century wars, most notably the American Civil War, where balloons provided observation

Voyager



The Rutan Model 76 Voyager was the first aircraft to fly around the world without stopping or refueling. It was piloted by Dick Rutan and Jeana Yeager. The flight took off from Edwards Air Force Base's 15,000 foot (4,600 m) runway in the Mojave Desert on December 14, 1986, and ended successfully 9 days, 3 minutes and 44 seconds later, on December 23. The aircraft flew westerly 26,366 statute miles (42,432 km; the FAI accredited distance is 40,212 km)[1] at an average altitude of 11,000 feet (3,350 m).

First world war (1914-1918)



About 10 years after the Wright brothers made the first powered flight, there was still much to be improved upon. Because of limitations of the engine power of the time, the effective payload of aircraft was extremely limited. They were made mostly of hardwood (braced with steel wires) and linen fabric doped with flammable liquid to give them the stiffness required to form a wing surface.



As early as 1909, these evolving flying machines were recognised to be not just toys, but weapons. Major developments in machine gun synchronization created for the Germany fighters an edge over the French and British planes.





Aside from these primitive materials, the rudimentary aviation engineering of the time meant most aircraft were structurally fragile by later standards, and not infrequently broke up in flight especially when performing violent combat manoeuvres such as pulling up from steep dives.

Second world war (1939-1945)



Different from the fighters during the WWI, these airplanes no longer adopt bi-wing designs to reduce drag. Besides machine guns, these airplanes may also carry torpedo or other bombs.
Jet Fighters

A jet aircraft is an aircraft propelled by jet engines. Jet aircraft generally fly much faster than propeller-powered aircraft and at higher altitudes – as high as 10,000 to 15,000 meters (about 33,000 to 4t9,000 ft). At these altitudes, jet engines achieve maximum efficiency over long distances. The engines in propeller powered aircraft achieve their mtaximum efficiency at much lower altitudes. Jet aircraft can move faster than sound.
Stealth bombers



These aircrafts were designed to be invisible to radar and carry out their missions in the night. The Stealth Bomber, or B-2, is a long range bomber with the able to fly nearly undetected into enemy airspace, appearing as small as a bird on radar. It can carry large artillery, including nuclear bombs. It is effective at all altitudes, able to reach around the world in merely hours, and can fly 6,000 nautical miles (1,852 meters) without refueling.

The Stealth Bomber was to be a replacement for the B-52 bomber and took nearly 10 years and billions of dollars to develop. Northrop Grumman began delivery of the first functional B-2 bomber in late 1993. The United States Air Force (USAF) gave the stealth bomber a reliability grade of 90% for its first three years of use. Published assessments claimed that two stealth bombers could do the job of 75 other aircraft.





From a visual perspective, the stealth bomber's "flying wing" construction is truly unique. The body of the plane is remarkably narrow and flat, giving the appearance of virtually no body. The leading edges are angled at 33 degrees, while the rear edges form a "W" shape. The plane is coated in a black paint with radar-absorbing coating. The black color helps to keep the bomber hidden during nighttime missions.

The overall goal of the stealth bomber is to deliver weapons in a precision manner quickly without ever having to engage in combat. In order to achieve this goal, it has numerous design features. These deviations from conventional aircraft allow it to be nearly undetected in enemy airspace.

In order to go undetected, the stealth bomber must be extraordinarily quiet, from both a radar and an audio perceptive. The four engines are buried deep within the plane to muffle sound. Instead of releasing exhaust behind like a conventional aircraft, the B-2 cools its exhaust in a special chamber and then vents the cooled exhaust above the body. This keep it from being an easy target for heat-seeking missiles and protects is from ground sensors that would sense the heat from the bottom of the plane.

The cockpit holds two crew members. There are three settings for pilots to choose from: take-off mode, go-to-war mode, and landing mode. These three functions are changed by flipping a three way switch.

Weapons are held in bays in the center of the plane. It can carry 40,000 lbs (18,143 kg) of weapons at one time. These include conventional and nuclear bombs, precision-guided munitions.
